i did not expect the rook sacrfice. the queen sacrifise is obvious, looking at the position of th rooks. also, moving thenight anywhere and putting your otherrook down the side would have also mated. a very hard puzzle

The knight must go 2. Nd4+, where it attacks the f5 square. The knight cannot go 2. Ng3+, also attacking the f5 square, because it blocks the g1 rook.

The third move must be 3. Re8+, because if 3. Rg8+ Kxg8 4.Re8+ Kg7 5. Nf5+, black escapes with 5...Kg6.

Perhaps 3. Rg8+ can lead to an eventual mating net, but it will take a lot longer than the puzzle solution.
